LUIS W. PROEGEPJ, F PITTSBURGH, PENNSYLVANIA, ASSIGN OR OF ONE-HALF T0 CHARLES N. BRADY. OF WA$HINGTON, PENNSYLVANIA APPARATUS roe MAKING GLASS am'IcnEs.

To all whom it may concern Be it known that I, LUIS W. Pnonenn, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Making Glass Articles; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus forming hollow glass articles, such as bot.- tles, etc.

The object of my invention is to provide a a higher to a lower level in which transfer it is liable to become chilled.

To these ends my invention omprises the hovel features hereinafter set forth and 1n the accompanying drawlngs Figure 1 is a plan view of my improved apparatus; Fig. 2 is a'section on the line 22 F g. 1; Fig. 3 is a section onthe line 33 Fig. 1.; Fig. 4 is a bottom plan view of the table with molds removed and Fig. 5 is an'enlarged sectional view showing the means for opening and closing the molds, the star wheel being omitted; Fig. 6 is a section on the line 6-6 Fig. 5; and Figs. 7 andv 8 are details. I I

Referring to the drawings, the numeral 2 designates suitable standards upon which the bed-plate 3 is supported. This bed-plate has the vertical shaft 4 supported thereen. The casting 5 engages the shaft 4 and rests upon the plate 3 and in said the ball-bearing for the rotary table 8. An

intermittent rotary movement is imparted to the table 8 in the following manner; A suitable motor 9 is supported by the bedplate 3 and the worm 10 driven by said motor engages the worm-wheel 11 which is mounted on the shaft 12. This shaft 12 passes up through the sleeve 13 in the hubportion 14 of the plate. These parts are inclosed by the casing 15. The sleeve 13 Specification of Letters Patent.

has the flange 16 with the ball-bearing 17 which is engaged by the hub-portion 18 of the segment 19 which is secured by the jamb nut 20 to the shaft 12. The segment 19 carries the arm 21 which has the roller 22 at its outer end adapted to engage the slots orrecesses 23 in the star-wheel 24 securediito the table 8, whereby an intermittent mbvement is imparted to the table 8 by the engagement of the arm 21, while the segment 19 engaging the spaces intermediate the points of the star-wheel acts to lock the star-wheel against movement when not engaged by the arm 21.

A sleeve 25 surrounds the vertical shaft 4 and is secured to the table 8. A spider 26 is carried on the sleeve 25 and is secured thereto so as to rotate with the table 8. The spider 26 carries at its" extremities the blow- These blow mold devices are composed of the swinging arms 28 which are mounted on the pin 29. The arms 28 have the toothed portions 30 which are engaged by the racks 31 and 32 at different levels to engage the toothed portions 30 of arms of the blow-mold which-are arranged one above the other. The racks 31 and; 32 form part of the arm 33 which is adapted to move back and forth in the spider-arm. This movev ment is imparted to the arm 33 by means of the stationary cam 34 on the shaft 4, said cam having the cam-way 35 which engages the projection36 which passes through the slot 37in the spider-arm. "This projection 36 is screwed into the sleeve 38 which is adapted to engage the shoulder 39011 the arm 33 when the cam operates to open the mold as fully hereinafter set forth. A spring 40 is interposed between the sleeve 38 and a collar 41 on the end of the arm 33, said spring acting to insure the tight closing of the mold as fully hereinafter set forth. The blow-mold halves 42 are secured to the arms 28 by the keys 43 and in this way difierent sized blow-molds may be attached to said arms.

' The blank-molds 44 together with the neck-molds 45 are arranged to be rotated and to provide for this rotation of the blank and neck-molds ll employ the following construction: The halves of the blank-molds are adapted to swing on the pin 44 connect ing the same and are secured by said pin to the vertically rotary frame 46. This rotary frame 46 is carried by the support 47 order to lock the sleeve 49 as well as the shaft-portion 50 of the frame 46 against accidental rotary movement, I provide the lock 55 which is adapted to engage therecesses 56 in the sleeve 49. This lock 55 is mounted on the support 47 and comprises the latches 57 which are connected to the sleeve 58 on the bolt 59 screwed into thesupport 47. A spring 60 is interposed between the sleeve 58 and the head 61 on the bolt 59 so as to normally force the latches into engagement with the recesses 56 of the sleeve 49. A'groove 62 is formed in the shaft-portion 50 and within said groove is the rod 63 which has the upwardly extending portion 64. Projecting out from the extension 64 are the racks 6,5 and 66 arranged at different levels and adapted to engage the toothed portions .67 on the arms 68 of the neck-mold 45. The rod 63 is slidable back and forth in the groove 62 and this is accom plished by the stud 69 on said rod engaged by the groove 70 in the pinion 53, which is loosely mounted on the shaft portion 50. This groove 70 is clearly indicated in Fig. 7

To provide for the opening and closing of the blank-mold I employ the rod 71 which is slidable in the passage 72 formed in the shaft-portion 50. The spring 73 surrounds the rod 72 and said spring is interposed be-' tween a collar 74 on said rod and a shoulder 7 5 on a slidable member 76. The rod 71 has the tail-piece 77 which engages a recess 78 in the slidable member 76. The member 7 6 has a roller 7 6 which is engaged by the groove 7 9 on the inner face of the pinion 52-. At the outer end of the rod 71 are the racks 80 which engage the toothed portions 81 on the arms 82 of the blank-mold 44.

The bottom plates 85 for the blow-molds are adapted to be thrown up into position to close the bottom of the blow molds just before the blowing operation, and this move ment of the bottom plates is accomplished in the following manner: The bottom plate 85 is secured to the rock-shaft 86 which is mounted in bearings 87. This rock-shaft 86' carries the pinion 88 which is engaged by the rack-bar 89 slidable in guides 90. An elongated pinion 91 is mounted in bearings 92 and engages the other end of the rack-bar 89. A vertical rack-bar 93 also engages the elongated pinion 91 and theupper end of said rack-bar is off-set and engaged by the pinion 52 as clearly indicated in Fig. 2. From this it will be apparent that when the pinion 52 said plate is in the naeaeee is rotated the vertical movement will be imparted to the rack-bar 93 and through said rack-bar rotary motion imparted to the elon gated pinion 91. Motion is transmitted from this pinion 91 to the rack-bar 89 and through said rack-bar to the pinion 88 on the rockshaft 86, .which will rock said shaft and raise or lower the bottom-plate 85. Secured to the upright 95 is the rack-plate 96 having the racks 97 and 98 which are in the path of and adapted to be engaged by the pinions 51 and 52 as the table 8 rotates. Another rack-plate 99 is carried by the uprights 10,0 and the rack 101 secured to the upper face of path of and adapted to be engaged by the plnion 53. Still. another rack-plate 102 is carried by the uprights 103 -has the cam 108 which is engaged by the roller 109 on the sleeve 58 was to raise said sleeve to release the locking device 55 and permit of the rotation of the blank and neck-mold as fully hereinafter set forth. Supported by the standard 95 and the central shaft 4 is the cylinder 110 which oper ates the closure 111 for closing the blankmold and for admitting air pressure to force the glass down around the neck-mold in the ordmary manner. A cylinder l12 is carried by the bed-plate 3 and said cylinder operates the closure 113 which enters the opening in the neck-mold to form the neck in the ordinary manner.

The operation of my improved apparatus in the forming of a bottle or like article is as follows: In Fig. *1 at the positionmarkedable manner and as soon as the mold has been charged the table 8 is moved by the motor around to the next position which is the point at which the blank is formed, the table moving in the direction indicated by the arrow Fig. 1. In this position the cylinders 110 and 112 are operated to bring the closures 111 and 113 into position for the admission of air, into the blank-mold and the neck-mold as indicated in Fig. 2. When the blank has been formed in this manner the table 8 again advances and in doing so the rack 97 is engaged by the pinion 51 which is rotated thereby and the shaft portion of the frame 46 is rotated and the blank-mold together with the neck-mold are rotated to invert the blank and neck-mold so that the neck-mold is above and the blankthe bottom plate 85.

mold below, in Fig. 2. When this has been accomplished the pinion 52 comes into engagement with the rack 98 and said pinion is rotated with two results, first, the movable member 76 is moved outwardly and with it the rod 71 engaged by said movable member, so that the racks 80 moving over the toothed portions 81 of the arms of the blank-mold will act to open the blank-mold. Second, the rotation of the pinion 52 will move the rack-bar 93 and through the connections above described the rock-shaft 86 is moved to bring the bottom-plate up into a horizontal position. The neck-mold, however, remains closed and the blank is suspended therefrom. The table continues to move with the blank-mold opened and the bottom plate 85 raised. Just before the third position of rest is reached, the cam 34'. acting on the projection 35 operates the racks 31 and 32 and moves the arms 28 of the blow-mold so as to close the blowmold around the blank, the neck-mold and bottom 'plate 85 cooperating with the halves of the blow-mold to form the complete mold. The blowing operation takes place at this point as indicated in Fig. 3 where the air passes from blowing mold, and the bottle is finished. The table 8 as it continues to rotate comes around in position where the pinion 53 engages the rack 101. This acts to move the rod 63 by the engagement of the projection 69 with the groove 7 0 in the pinion 53 and the racks 65and 66 are operated to open the neck-mold 15, while the cam 34. acts to open the blowmold leaving the bottle supported by the bottom plate 85. At this point the finished bottle is removed and on the next movement of the table 8 the pinion 53 engages the rack 104: which closes the neck-mold and practically simultaneously therewith the pinion 52 engages the rack 105. This acts to close the blank-mold and at the same time lowers The next step in the operation is the engagement of the pinion 51 with the rack 106 which results in the turning of the blank-mold Sindne'ck-tnold into their inverted or charging position, so that when the next stop of the table takes place the charging of the mold is agaln effected. Just prior to the turning of the blank-mold and neck-mold as above, the.

roller 109 on the sleeve 58 engages the cam 108 and the locking device 55 is released so as to permit of the rotation of the blank and neck-mold.

By having the blank-molds and blowmolds in the same or substantially the same horizontal plane or at the same level I greatly simplify the construction as well as the operation in that the blank does not have to be lowered into position to be surrounded by the blow mold, and that'there is not the same liability of the undue elongation of instead of in the position shown' cylinder 114 to the- T ticles,

the blank due to the lowering of it from a higher level to the blow-mold below. There is furthermore greater accessibility to the parts for repairs, renewals, etc.
